Well, she's got horrible base AS, which would definitly work against you. She has no steroid either, but she does have great escape mechanism. Distortion once to get some distance, mimic to get more, Chain to slow/root.
As such, I'd build her straight damage/ADC. Prospector, Berzerker, IE, LW, PD, Sanguine. You don't need any phage item to kite, and since her abilities all have fairly long cooldown, and aside from sigil you want to use them defensively for the most part, I don't think trinity would be the best route to take..
